This inventidn relates to a particular type of cloth which is especiallyusefulf for wearing apparel of men and'women. 1

It is rather harsh to the feel but has excel lent wearing qualities andit will not shrink as much as other cloth made of woolen fibers,

and will keep its shape much longer than most woven goods.

It ismade of twisted yarn or cables the warp and the filling beingsustantially the same, both being built up of a plurality of worstedthreads twisted beyond the point of greatest tensile strength and almostup to the breaking point. .16 This yarn after being so twisted is woundupon a spool and steam is forced through the yarn mass on the spooluntil it has been fully set. It is then dried. Yarn so twisted and setwill not kink but 30 is straight and firm. It will not untwist and hasvery little stretch either when wet or dry.

In the drawings, Fig. 1 is a plan View very much enlargedshowing a smallsection of cloth of my construction.

Fig. 2 is a very much enlarged plan view of one of the strands oftwisted yarn-ofmy invention. I

Fig. 3 is a vertical sectional view'showing a spool being steamed in mypreferredfmanleft as on f the her. This is a view from the line 3-3 ofFig. 4.

Fig. 4 is an end elevation as fromthe right of Fig. 3. l 1

In the drawings, A represents'Fthe warp and .B the filling, or Brepresents-the warp and A the filling as both are made of substantiallythe-same yarn.

In'Fig. 2, I show a yarn built up of two threads 10and 11 which threadshave been .gspun in the usual manner. I I

These threads 10 and 11 are twisted on a twisting frame beyond the pointof greatest tensile strength and almost to the breaking point. 7

After being so twisted or in thezprocess of twisting theyare wound on aspool such as F having the heads 20 and 22 with a barrel 24 throughwhich are a large number-of ;perforations 25. Preferably one end 23 isclosed the yarn mass indicated at while 'froni end21 extendsthe pipe pto ajvaeuum lnachine which sucks the air out [from the-inside of barrel24. f5 "jThe-whole device is'preferably enclosed in a casing K intowhich'by means of a pipe H steam s introduced at; the same time thatthe'vacuum is being created by the pipe G. The result is that. cleansteam' passes through B, passing out through the holes 25 and the pipeG. i The end 23 of spool barrel 24 is preferably closed by a plug 25 andthe casing K, as shown, rests on supports 35, 35, and is generally ofcylindrical form as at 36 having the closed end 37 through which exhaustpipe Gfpasses, and an open end '38 which can be close by thedoor-401hinged at 41 and having a latch or closing member 42 whereby itmay be made tight while the operation is proceeding.

shown, the spool F carrying the yarn mass B is slid into place on therails 30 and 32 carried by supports 31 and 33 until the end21 of spoolbarrel 24 engages the end 9 of pipe G.
